I have tried every tool available to try and increase my battery life. In windows I can get up to 8 hours but in linux I can barely manage 4. I am using powertop, thinkfan, tcp, updated every driver, and turned off unnecessary things.

Is there ANYTHING else I can do to increase my battery life?

do you have an Nvidia card with optimus technology? If so, Bumblebee doubled my battery life for me (2 hours to 4). –  don.joey Mar 26 '13 at 17:03
No, I do not have an Nvidia card –  user67784 Mar 26 '13 at 18:05
